CSS Second Child

We will comprehend the CSS second child in this article. Let us understand what the second child is.

Second Child

The second child in CSS is the child related to the second number. Let us comprehend it with the assistance of a demonstration.

Demonstration

The code given below contains a "div" element that is a parent. The "div" element consists of many children. The "p" element written directly after the parent is considered the first child, and the next "p" element is considered the second child.

Code:

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Demonstration of CSS second child</title>
</head>
<body>
    <div class="parent">
        <p> 1st Child </p>
        <p> 2nd Child </p>
        <p> 3rd Child </p>
        <p> 4th Child </p>
        <p> 5th Child </p>
        <p> 6th Child </p>
    </div>
</body>
</html>

Output:

Here is the output in which we can clearly witness the second child.

We can pick the second child of the parent with the help of :nth child() selector.

:nth Child() Selector

It is a pseudo-class selector used to match the nth-child element. It allows us to select any child of the parent and give any style to the element.

Syntax:

Name of the element:nth-child(n) {
    CSS declarations;
}

The name of the child element should be written at the start of the syntax. "n" is the number, odd keyword, even keyword, or formula.

Demonstrations of :nth-child() Selector

We will comprehend the :nth-child() with the help of demonstrations.

Demonstration 1:

In this demonstration, we will choose all the children one by one and apply style to them. We will create a list of 10 electronic appliances and select each item using nth-child() to give it different colors.

Code:

<!DOCTYPE html>
<html lang="en">
<head>
    <title>Selecting child</title>
    <style>
        li:nth-child(1) {
            color: red;
        }
        li:nth-child(2) {
            color: pink;
        }
        li:nth-child(3) {
            color: tomato;
        }
        li:nth-child(4) {
            color: green;
        }
        li:nth-child(5) {
            color: rebeccapurple;
        }
        li:nth-child(6) {
            color: firebrick;
        }
        li:nth-child(7) {
            color: violet;
        }
        li:nth-child(8) {
            color: teal;
        }
        li:nth-child(9) {
            color: lightblue;
        }
        li:nth-child(10) {
            color: hotpink;
        }
    </style>
</head>
<body>
